| Cornet/trumpet mouthpiece adaptors are, by and large, a very, very poor substitute for a trumpet mouthpiece. (The exceptions would mostly be situations where the adaptor is designed specially for a given mouthpiece, as is the case with the GR piccolo trumpet mouthpieces -- although I'm not sure I buy the idea even then.) You will almost always find that the intonation is severely compromised, and that the upper register is more difficult than it ought to be. You can get a Stork 3B trumpet mouthpiece (which will be exactly the same mouthpiece except with a trumpet shank) for under $50. It won't be gold-plated, but I would virtually guarantee that it will play more than $40 better than a cornet mouthpiece with an adaptor. |
